  1. Change tillage practices

    A replicated experiment from 1988 to 1998 on a loamy-sandy loam soil in Woburn, England (Quinton & Catt, 2004) found that there were no major differences in soil loss between minimal and standard tillage treatments. Soil loss was lower on across-slope plots (148 kg/ha) compared to up-and-downslope plots (262 kg/ha). Runoff was also lower in across- (0.82 mm) than up-and-downslope plots (1.32 mm). Crop yields were higher on across-slop plots than on the up-and-downslope plots, in 10 of 11 years tested. The experimental crop was a potato Solanum tuberosum/barley Hordeum vulgare/wheat Triticum aestivum/sugar beet Beta vulgaris/fallow (not specified) rotation. The main treatments were cultivation direction (up-and-downslope, across-slope) and tillage (minimal with some residue retention, conventional mouldboard ploughing with all residue removed). There were two replicates of four 25 x 35 m plots. Soil loss, runoff and yield were measured.
